Data Communications Module, 2nd Edition, 2/03
The D2–DCM can be used in either a point-to-point or multi-drop configuration. A
point-to-point connection only has two stations, a master and a slave. Use the
point-to-point configuration to connect a personal computer, an operator interface,
or an intelligent device to a single D2–DCM. You must also use this configuration
when you want to connect a
Direct
NET master station to a single
Direct
NET slave
station.
Use the multi-drop configuration to connect one master to two or more slaves (90
slave maximum).
